k7m - many reboots during windows startup

Hi,

whenever I turn on my PC (Asus K7M / 1000 Mhz) it reboots 3 to 4 times
during the start of Windows XP. After finally bringing up the desktop of XP
it runs rock stable til I turn off my system for some hours or overnight.
Then I have the same problem again and the system needs some reboots to
finally enter windows xp.

I tried with different CPUs, with different RAM-Chips but there is no help.
Why does my machine only make problems when it is cold ? I can turn my PC
off and restart after half an hour without problems.

Any Ideas ?

Thanx,

Simon

* dying PSU
* capacitor problems (look out for leaking ones)
* short circuit somewhere (like a mounting standoff shorting out
something)
